Sperry Glacier Panorama

Sperry Glacier Panorama

In 1913, Sperry Glacier's mass spanned across the entire basin and the glacier's terminus (the end or bottom part of a glacier at any given point in time) was recorded at over 150 feet tall. Contemporary images show how the glacier has receded and separated into fragments.
